There haven’t been many significant leaks this year, which makes me think it probably is a lot of under the hood fixes and improvements.
Notifications on iOS is a big one people mention, mostly in comparison to Android. I’ve been iOS exclusive for a long time so never really noticed a problem, but I’m willing to believe they can be done better.
I’d like to see better DND options. Letting some apps bypass general DND settings, or keeping them on even if the screen is unlocked. There’s nothing worse than playing a game or watching a video on your phone or ipad and having notification banners pop up constantly.
Siri is definitely due an overhaul, and hopefully they’ll continue to do this incrementally throughout the year and not just annually. I’m a HomePod user (and a very happy one) and she does everything I need, but there are some bits that are more fiddly than they should be. I like Alexa’s ‘Good Morning’ thing where she reads the news and weather. If you ask Siri for the news, she spends a minute telling you all the alternative channels it can fetch news from too, when I just want her to get on with it.
I’d also like ‘Her Siri’ to be more intelligent when there are lots of devices around. Sometimes more than one will chime then all but one will go blank, and whether the task can be carried out depends on which is listening. If I say ‘Hey Siri, call mum’ but my HomePod picks it up and it can’t make a call, it should be smart enough to hand the task off to the phone where a call can be made. Also, give the iMac always-on Siri like the HomePod. It’s mad with all the power in a desktop computer, you can’t do much with Siri.
